What cardiovascular issue is characterized by leg swelling?

Leg swelling can often be associated with various cardiovascular issues, particularly conditions that affect venous return or result in fluid retention. One of the main cardiovascular problems that can lead to peripheral edema, which includes swelling in the legs, is congestive heart failure (CHF). In CHF, the heart's ability to pump blood effectively is compromised, leading to increased pressure in the veins and eventual fluid buildup in the legs.

While chest pain can signify a cardiovascular issue, it is not directly characterized by leg swelling. Conversely, shortness of breath (SOB) may occur with cardiovascular issues but also does not specifically indicate leg swelling. Abdominal pain and anxiety are symptoms that may be present in various medical conditions but do not pertain directly to swelling in the legs. Therefore, understanding that leg swelling is mostly linked to heart-related issues helps identify the most relevant cardiovascular condition.
